CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit under 35 U.S.C. §119(e) of provisional application No. 61/904,136, which is hereby incorporated by reference.

TECHNICAL FIELD

This invention relates generally to button fasteners on articles of clothing which may be easily attached and detached from the article.

BACKGROUND

This invention relates generally to button fasteners on articles of clothing which may be easily attached and detached from the article.

Some articles of clothing may require a significant investment of resources, for example, a blazer or jacket. Often, an owner of a blazer or jacket may enjoy wearing it with a type of button for some occasions or venues that is not desirable for other occasions or venues. For example, gold or silver buttons on the blazer might be preferred at some times, while wood or bone buttons might be preferred at other times.

It is well known that buttons are conventionally sewn to articles of clothing using thread or something similar. This type of attachment tends to be permanent, however, and at the very least, does not allow the buttons to be easily changeable. Some garment owners may lack the sewing skill needed to change conventionally sewn buttons. Even if the owner has sewing skills, the task of removing and replacing buttons is time-consuming, and repeated sewing at the site of the button may damage the fabric. Inability to change buttons at will can thus limit the versatility and use of an article of clothing.

Thus, there is a need in the prior art for a system and method for providing a button that can easily be attached and detached from an article of clothing.

SUMMARY

According to an aspect of the invention, there is provided a detachable button system having a fixed or permanent component permanently or semi-permanently attached or fastened to a garment or other article, and at least one detachable component that is normally securely attached to the fixed component. The fixed component has a first attachment element. The detachable component has a second attachment element adapted to cooperate or mate with the first attachment element to allow any of the detachable components to be easily detached from, or attached to, the fixed component, without additional sewing or other permanent attachment steps. The detachable components may have the general shape of the outer-facing part of conventional buttons, including ornamentation. Thus, a detachable component having a first ornamental appearance, can be detached from the fixed component, and another detachable component having a different ornamental appearance, attached to the fixed component, providing the effect of changing buttons, without the need for sewing or another permanent attachment step.

According to an aspect of the invention, the fixed component is realized as a base plate fastened to an article of clothing; the detachable component is realized as a button; the first attachment element is realized as an abutment cylinder extending from the base plate; the second attachment element is realized as a pin extending from the button and adapted to receive the abutment cylinder. Arms extend radially from the pin to form a pin catch; an opposed pair of J-shaped slots in the abutment cylinder receive the pin catch. In operation, to install the button, the pin is inserted into the abutment cylinder to stop points at the short end of the J-shaped slots. A spring in the abutment cylinder opposes insertion of the pin therein. Islands formed by the curves of the J-shaped slots cooperate with the spring pressure to form a detent which keeps the pin catch secured against the stop points. To remove the button, the button is pushed down toward the base plate and twisted slightly to push the pin catch past the islands into the long part of the J-shaped slots, whereby the button can be raised and the pin and pin catch is released from the abutment cylinder.

According to a further aspect of the invention, the fixed component is realized as a shank portion to which an abutment cylinder, as previously described, is attached and from which it extends. The shank portion is fastened to an article of clothing, e.g. by sewing.

According to a further aspect of the invention, the abutment cylinder is threaded, and the pin is correspondingly threaded so that it may be screwed into the abutment cylinder.

According to a further aspect of the invention, the first attachment element is be realized either as one of an abutment cylinder or a pin with a pin-catch, and the second attachment element is realized as the other one of the abutment cylinder or pin with the pin catch.

DETAILED DESCRIPTION

FIG. 1 depicts schematically a detachable button system 100 constructed according to an aspect of the present invention, according to which the detachable button system 100 has a fixed or permanent component 120 permanently or semi-permanently attached or fastened to a garment or other article 160, and at least one detachable component 140 (of which only one is shown) that is normally securely attached to the fixed component 120. The fixed component 120 and the detachable component 140 are shown in FIG. 1 in a detached configuration, but in ordinary use, these components are attached to form a button which can be employed as an ornament or can function, for example, as a closure of a garment or to secure plural layers of cloth or similar articles.

The fixed component 120 has a base element 122 and a first attachment element 124 extending therefrom. The base element 122 is permanently or semi-permanently attached or fastened to a garment or other article 160 (hereafter, “garment” is intended to refer to a garment, cloth, or other flat article with which a button may be used) by any appropriate attachment or fastening means, such as thread 128 sewn through holes or slots 126 or around appropriate tabs or shanks of the base element 122. The base element 122 could also or instead be attached or fastened to garment 160 using staples, crimped claws or other parts of the base element, or using an adhesive, glue, weld, or similar bond 130, or any other appropriate fastening.

The detachable component 140, which may be considered the “button”, has an button head element 142 facing away or outward from garment 160 and a second attachment element 144 adapted to cooperate or mate with the first attachment element 124 to allow any of the detachable components 140 to be easily detached from, or attached to, the fixed component 120, without additional sewing or other permanent attachment steps.

FIG. 1 is intended as a schematic representation of the button system in which shape and relative sizes may be distorted, and detail omitted, for simplicity of explanation; details of various embodiments of the button head element 142, base element 122, and the attachment elements 124 and 144 are described further.

The detachable components 140 may have the general shape of the outer-facing part of conventional buttons, including ornamentation. Where the button system 100 is to be used as a closure, the button head element 142 preferably has a diameter larger than that of the attachment elements 124 and 144 so that the button head element 142 may interfere or capture the portion of a garment (not shown) surrounding a button hole or slot therein.

Thus, a detachable component 140 having a first ornamental appearance, can be detached from the fixed component 120, and another detachable component having a different ornamental appearance, attached to the fixed component 120, providing the effect of changing buttons, without the need for sewing or another permanent attachment step.

An embodiment 200 of a detachable button system as generally described in connection with FIG. 1, constructed according to an aspect of the present invention is shown in FIGS. 2-6.

The detachable button system 200 includes two portions, one 210 that is permanently attached to an article of clothing, and another 410 that may be attached and detached as desired. The permanent portion 210 is best seen in FIGS. 2-3, in which fixed component 120 of FIG. 1 is realized as a permanent portion 210; FIG. 2 is a top plan view of the permanent portion 210; FIG. 3 is a side view of the permanent portion 210; base element 122 of FIG. 1 is realized as a base plate 212; and first attachment element 124 of FIG. 1 is realized as an abutment cylinder 214;

Base plate 212 includes a number of holes 216 through which thread or similar material can pass for the purposes of attaching base plate 212 to the underside or topside of fabric or other material 610 (See FIG. 6).

Element 214 is an abutment cylinder. The abutment cylinder 214 has a set of J-shaped slots 218. One slot 218 is shown in FIG. 2 while a second slot (not shown) is disposed on the opposite side of cylinder 214. The slots are designed to receive a pin catch 416 on the detachable button portion 410 (FIGS. 4-6), described in more detail below. Element 220 indicates the stop point of slot 218. This stop point 220 holds the pin catch 416 under pressure from spring 222.

The detachable or button portion of the embodiment 200 the detachable button system is best seen in FIGS. 4-5, in which detachable component 140 of FIG. 1 is realized as a detachable portion 410; FIG. 4 is a bottom view of the detachable portion 410; FIG. 5 is a side view of the detachable portion 410; button head element 142 of FIG. 1 is realized as button head 412; and second attachment element 144 of FIG. 1 is realized as pin 414 and pin catch 416.

Button portion 410 may be used with the permanent portion 210 of FIGS. 2-3.

The underside of a button part of the detachable portion 410 is indicated at 422. Pin 414 extends perpendicularly from the underside of the button and includes a pin catch 416 on either side of pin 414. The pin catches 416 extend slightly further out from the width of abutment cylinder 214 (FIGS. 2-3, 6), thereby allowing pin 414 to be inserted into the abutment cylinder 214 only when both pin catches 416 are directly over both slots 218 of the abutment cylinder 214. As best seen in the side view, element 418 is the top of the button.

FIG. 6 is a hybrid side and cross-section view of the embodiment 200 of FIG. 2-5, showing the permanent portion 210 and the detachable button portion 410 combined in the attached configuration.

In this view, detachable button portion 410 having pin 414 is pushed downward into abutment cylinder 214. Surplus portion 420 of pin 414 extends below the slots in abutment cylinder 214, thereby compressing spring 222 and causing pin catches 416 to press against the top of stop points 220 element 15 of FIG. 1A. Then, as pin catch 416 moves through slot 218 and up towards top point 220, the spring 222 pushes back up against the pin 414, locking the pin 414 in place within the abutment cylinder 214. The action of locking the button into the abutment cylinder also requires a slight twist. To remove the button detachable button portion 410 from the permanent portion 210, the button is pushed and twisted in the opposite direction, allowing pin catches 416 to move back through slot 218 and out of abutment cylinder 214.

FIG. 6 also shows the position of base plate 212 placed against the side of material 610 that is opposite button 410. It is attached with thread 612 through the holes 216 (see FIG. 2). In an alternate embodiment, base plate 212 can be attached on the other side of material 610, in other words, on the same side as button 4. In the first case, base plate 212 is effectively attached on the inside of an article of clothing. In the alternate embodiment, it is attached on the outside of an article of clothing.

The button system embodiment 1100 of FIGS. 11-14 may generally be constructed as earlier described in connection with the embodiment 200 of FIGS. 2-6, modified as described below. Accordingly, the embodiment 1100 of FIGS. 11-14 should be considered to inherit the characteristics and foregoing description of the embodiment 200 except as described below.

FIG. 11 is an oblique view of the detachable button system 1100. FIG. 12 is a view of the detachable button system 1100 taken from another angle. FIG. 13 is a side view of a fixed or permanent portion 1120 of the detachable button system 1100. FIG. 14 is a top view of the fixed or permanent portion 1120 of the detachable button system 1100.

As best seen in FIG. 11, detachable button system 1100 comprises a permanent or fixed portion 1120 and a detachable button component 1140, which are adapted to be attached, coupled, or mated, in which configuration the button system 1100 may to serve as a button, which may provide a functional closure for a garment or other article, or may be solely ornamental. The permanent or fixed portion 1120 comprises a base plate 1122 and a and an abutment cylinder 1124. The detachable button component 1140 comprises a button head 1142 and an attachment pin 1144. The button head 1142 has an inner surface 1192, i.e., a surface facing toward the garment when the button system 1100 is assembled and installed, and an outer surface 1190, i.e., a surface facing away from the garment. The base plate 1122 has top surface 1186, i.e., a surface facing toward the button head 1142 when the button system 1100 is assembled, and a bottom surface 1188, facing away from the button head. The attachment pin 1144 is attached to or integrally formed with the button head 1142 at the inner surface 1192 and generally extends away therefrom. The abutment cylinder 1124 is attached to or integrally formed with the base plate 1122 at the top surface 1186 and generally extends away therefrom.

Comparing the features of the detachable button system 100 of FIG. 1 described more generally above, to those of button system 1100 of FIGS. 11-16, the fixed component 120 of FIG. 1 is realized as permanent or fixed portion 1120; base element 122 of FIG. 1 is realized as permanent or fixed portion 1120; and the first attachment element 124 of FIG. 1 is realized as abutment cylinder 1124. Likewise, the detachable component 140 of FIG. 1 is realized as detachable button component 1140; the button head element 142 of FIG. 1 is realized as button head 1142; and and the second attachment element 144 of FIG. 1 is realized as pin 1144.

The base plate 1122 is preferably attached to a garment or other article 1198 (FIG. 13) using any appropriate attachment or fastening means. The base plate 1122 may be formed as a generally-disc-shaped member. The base plate 1122 may have apertures 1126 or other structures such as legs, stakes, or crimpable claws (not shown) to accommodate attachment or fastening of the base plate 1122 to garment 1198 on a permanent or semi-permanent basis. For example, base plate 1122 may be sewn to the garment or other article 1198 using thread, wire, or another filament material, shown schematically as item 1128 (FIGS. 12-13). Base plate 1122 could also be stapled to the garment or other article 1198. If legs, stakes, or crimpable claws are provided, such components may be mechanically shaped or formed at the time of installation to provide a secure attachment. The base plate 1122 could also be attached to garment or article 1198 using an adhesive, cement, or by welding, as represented by item 1196 (FIG. 13). Although base plate 1122 is shown and described as disc-shaped, other shapes could also be used, including oval, square, or triangular, or the like. The diameter of the base plate is preferably large enough to allow forces associated with the use of the button to be distributed over a large enough area of the garment or article 1198 to avoid damage over the lifetime of the garment.

Attachment pin 1144 of the detachable button component 1140 comprises a trunk or body portion 1152 having an end at 1154. The abutment cylinder 1124 of the permanent or fixed portion 1120 forms an opening 1180 (FIG. 14) to receive the mating attachment pin 1144 of detachable button component 1140. The end 1154 of pin 1144 may be narrowed to facilitate insertion of the end into the abutment cylinder opening 1180. Pin 1144 has at least one structural feature adapted to cooperate with a feature of abutment cylinder 1124 to detachably retain the pin 1144 in a coupled or mated relationship with the abutment cylinder 1124, and therefore to detachably retain the detachable button component 1140 and the permanent or fixed portion 1120 in a coupled or assembled relationship. As best seen in FIG. 12, pin 1144 comprises a pair of pin catch arms 1156 extending radially from the body portion 1152 near the end 1154 thereof. As best seen in FIGS. 13-11-14, the abutment cylinder 1124 comprises a pair of slots 1170 for receiving and retaining the pin catch arms 1156. The slots may, for example, be shaped to help retain the pin catch arms 1156 in an “assembled” position. For example, each of slots 1170 may have a modified “J” shape extending longitudinally from an opening 1174 at the top of the abutment cylinder 1124 toward the base plate 1122; then extending circumferentially for a short extent; and then extending longitudinally away from the base plate, ending at a stop location 1172. A spring 1194 is provided in the interior of the abutment cylinder to bear upward against the end 1154 of pin 1144.

In operation, when the detachable button component 1140 is installed on the permanent or fixed portion 1120, the pin catch arms 1156 are received in the pin capture slots 1170 and travel longitudinally therealong, until the arms 1156 reach the bottom of the “J” shaped slots. The detachable button component 1140 is rotated or twisted to cause the arms 1156 to travel along slots at the base of the “J” to reach the truncated longitudinal sections thereof, and then allowed to travel longitudinally upward therealong, away from the base plate 1122, to rest at the stop locations 1172. Pressure from the spring 1194 keeps the arms 1156 at the stop locations 1172, and the shape of the material of abutment cylinder 1124 forms an interfering ridge that prevents the arms from rotating away from the stop locations 1172 absent pressure to overcome the spring 1194.

In order to release or detach the detachable button component 1140, the user may depress the button to overcome pressure from the spring 1194 to push the pin catch arms 1156 to the base of the “J”-shaped slots, and then rotate the arms 1156 to reach the open portions of slots 1170, whereby the detachable button component 1140 may be released.

Spring 1194 may be realized using any appropriate spring or other resilient component, such as a coil spring, leaf spring, resilient foam, or other resilient material. Spring 1194 could also be a torsion spring; the end 1154 of pin 1144 could be modified to engage spring 1194 such that it resists the rotation of the pin catch arms 1156 necessary to release the arms from the abutment cylinder pin capture slots 1170.

Although embodiment 1100 is described herein as comprising two abutment cylinder pin capture slots 1170 and two pin catch arms 1156, some other number of slots and arms could also be used. Other shapes could also be used for the pin capture slots 1170, and arms 1156 and slots 1170 could be modified in complementary ways so that the detachable button component 1140 may accept and detachably retain the permanent or fixed portion 1120 in an assembled configuration.

There is shown in FIGS. 15-16 another embodiment 1500 of a detachable button system constructed according to a further aspect of the invention. The embodiment 1500 may generally be constructed as as earlier described in connection with the embodiment 1100 of FIGS. 11-14 with the modifications hereinafter described.
